A military source told AFP that “millions” of protesters took to the streets. “It is the biggest protest in Egypt’s history.”

Opposition leaders are calling for the resignation of the Muslim Brotherhood leader, the dissolution of Egypt’s Islamist-dominated elected parliament, and the shelving of Islamist-drafted constitution to set up a new round of elections and a new constitution.

Morsi’s supporters, celebrating the 61-year-old’s first anniversary in office, have gathered to defend the president while accusing the opposition of engaging in a conspiracy to oust an elected ruler.

The political turmoil has pitted Islamists against liberal and secular activists, old regime loyalists, and the nation’s increasingly disenchanted poor.

The police are absent, after previously saying they would “not provide protection for any party or political headquarters.” Many are bracing for the worst in terms of violent clashes.

“Helicopters passed over growing masses of protesters across the country, prompting cheers from the anti-Morsi activists, many of whom say they hope the military will intervene to help them oust the president.”
